Back when I used to run the EB410.1 I found it necessary to upgrade to the VRP carbon towers which offered +3mm higher holes which allowed a lower ride height for turf, in addition they added lower holes on the camber link mounts to get a higher roll center than the stock tuning window. The stock plastic towers were not as durable as the carbon towers when taking a nasty wreck you're more likely to snap the plastic towers, seen this happen to lots of folks, and very seldom seen carbon towers break.

In contrast, I'm hearing some folks prefer the extra flex from the plastic towers to get a little more grip on dirt so I think it depends on track condition and what setup you need as to which option makes sense for you.
